Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31628126, here are decompositions:

37 + 31628089 = 31628126
109 + 31628017 = 31628126
157 + 31627969 = 31628126
199 + 31627927 = 31628126
223 + 31627903 = 31628126
373 + 31627753 = 31628126
487 + 31627639 = 31628126
499 + 31627627 = 31628126

Showing the first eight; more decompositions exist.
